# Stage synthesis and native cost profile

Research/results commit: https://github.com/wang-mengdi/variational-films/tree/7d79a0f
Frozen native probe commit: 9e1b66a; protocol.json records all source/input hashes.
Scripts: thin_film/scripts/cost_profile/.
Four frozen snapshots, no complete trajectory rerun, no solver optimization.
8 raw CSV/JSON files in one byte-exact ZIP; restore and SHA256 manifest included.
Actual-layout PNG/PDF reused byte-for-byte from ../global-space/.
New plots derived from recorded native timings and frozen original comparisons.
Independent physical flux/traction, full global convergence and original C1
physical/experimental predictions remain open. No >2h job launched.
